Legal claims defining the scope of protection, as filed with the USPTO.
1. A liquid crystal display, comprising: a pixel representing an image; a data gray signal modifier receiving n-bit gray signals from a data gray signal source, and generating first modified gray signals based on m-bit gray signals of the present and previous frames among n-bit gray signals (n>m. n and m are integers), and outputting n-bit gray signals based on the first modified gray signals; and a data driver which generates corresponding data voltages based on the first modified gray signals and outputs image signals to the pixel.
2. The liquid crystal display of claim 1 , wherein the m-bit gray signals are signals referencing orderly from a most significant bit among the n-bit gray signals.
3. The liquid crystal display of claim 2 , wherein the first modified gray signals are equal to or greater than m-bit of the n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are greater than n-bit gray signals of the previous frame.
4. The liquid crystal display of claim 3 , wherein the first modified gray signals are equal to or smaller than m-bit of the n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
5. The liquid crystal display of claim 2 , wherein the first modified gray signals are equal to or smaller than m-bit of the n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
6. The liquid crystal display of claim 1 , wherein the first modified gray signals are equal to or greater than m-bit of the n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are greater than n-bit gray signals of the previous frame.
7. The liquid crystal display of claim 6 , wherein the first modified gray signals are equal to or smaller than m-bit of the n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
8. The liquid crystal display of claim 1 , wherein the first modified gray signals are equal to or smaller than m-bit of the n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
9. The liquid crystal display of claim 1 , the data gray signal modifier further comprising a look up table in which at least one of the first modified gray signals is stored.
10. A liquid crystal display, comprising: a pixel representing an image; a data gray signal modifier receiving n-bit gray signals from a data gray signal source, and generating first modified gray signals based on m-bit gray signals of the present and previous frames among n-bit gray signals and generating second modified gray signals adding (n-m)-bit gray signals of the n-bit gray signals to the first modified gray signals (n>m. n and m are integers); and a data driver which generates corresponding data voltages based on the second modified gray signals and outputs image signals to the pixel.
11. The liquid crystal display of claim 10 , wherein the m-bit gray signals are signals referencing orderly from a most significant bit among the n-bit gray signals.
12. The liquid crystal display of claim 11 , wherein the second modified gray signals are equal to or greater than n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are greater than n-bit gray signals of the present frame.
13. The liquid crystal display of claim 12 , wherein the second modified gray signals are equal to or smaller than n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
14. The liquid crystal display of claim 11 , wherein the second modified gray signals are equal to or smaller than n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
15. The liquid crystal display of claim 10 , wherein the second modified gray signals are equal to or greater than n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are greater than n-bit gray signals of the present frame.
16. The liquid crystal display of claim 15 , wherein the second modified gray signals are equal to or smaller than n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
17. The liquid crystal display of claim 10 , wherein the second modified gray signals are equal to or smaller than n-bit gray signals of the present frame, when the n-bit gray signals of the present frame are smaller than n-bit gray signals of the previous frame.
18. The liquid crystal display of claim 10 , the data gray signal modifier further comprising a look up table in which at least one of the first modified gray signals is stored.
